- This paper introduces a new class of energy harvester for generating power from human body motion. Kinetic energy is captured by a rotational proof mass, as in a self-charging watch. However, the device employs piezoelectric transduction with up-conversion rather than electromagnetic transduction, resulting in an extremely low component count (7 parts). The work has been followed up by a number of groups, most notably the group of S. Roundy (Univ. Utah) which has carried out theoretical studies on variants of the design. A patent on the design has been granted in the US, Europe and China [US9893653(B2) and related]
